inorganic chemistry - Why is the Si-F bond one of the strongest single ...
Dec 22, 2019 · I honestly have no clue where to begin explaining why the Si-F bond is one of the strongest single covalent bonds of them all. I would actually predict the bond to be relatively weak on …
Reaction of Silicon Dioxide with Hydrofluoric Acid
Jul 20, 2020 · If you are using comparative bond strengths to determine if a reaction is favorable, you need to consider the bonds in the products as well as those in the reactants. Although H-F has a …
Why is covalent bonding stronger than electrostatic attraction?
Dec 16, 2014 · The article by Gillespie argues you should avoid the phrase "ionic character" because "ionic" and "covalent" aren't mutually exclusive. It's pretty clear from dipole moment in diatomic LiF …
Why do non-metals not form Ionic bonds (Ti-C, Sc-P) and instead form ...
Apr 19, 2022 · As Poutnik describes in his answer, low-electronegativity nonmetallic such as boron form bonds with low ionic character because in general, their atoms are not strongly electronegative …
organic chemistry - Why is the carbon-fluorine bond stronger than the ...
Jan 3, 2017 · From wikipedia article of carbon-fluorine bond, The high electronegativity of fluorine (4.0 for F vs. 2.5 for carbon) gives the carbon–fluorine bond a significant polarity/dipole moment. The …
halides - Why is fluorine more reactive than iodine despite the weaker ...
Silica is readily attacked by $\ce {HF}$ not because it is a strong acid, but rather because of the strength of $\ce {Si-F}$ bond thus formed. That deals with the thermodynamic parts of "reactivity", in the …
How much can we extend the Finkelstein reaction?
May 25, 2023 · They need something like a silane to activate them because the Si–F bond is of a competitive strength. Yes, the Finkelstein can work in other solvents, especially with the correct …
If a molecule has both polar and ionic bonds in it, is it polar or ...
Dec 5, 2016 · Beyond what @Mithoron said, remember that these molecules won't be planar -- they're tetrahedral. So, e.g., the 'horizontal' $\ce {Si\!-\!Cl}$ bonds don't cancel each other out -- they'll still …
organic chemistry - Bond dissociation energy order for C−C, N−N, …
Aug 1, 2018 · Noteworthy exceptions are single bonds between the period 2 atoms of groups 15, 16, and 17 (i.e., $\ce {N, O, F}$), which are unusually weak compared with single bonds between their …
Is there any chemical that can destroy PTFE or Teflon?
Jul 20, 2015 · However, carbon-fluorine is second only to the Si-F bond. Is there an "overclocked" Teflon made of silicon-fluorine bonds that is even stronger? Now I know that some, but very few, solvents …
